Looking around examples exist of companies paying people far above average, treating employees like people and providing opportunities for them to move up along with strong benefit packages. The companies that do this have been profiting, provide great value to the customer and IMO will outlast/beat out the slavedrivers.
First example is chick fil a. I still go to other fast food places, but only ones I have experience with and know that location will make my food right, not forget shit and the employees will be friendly/generally give a shit. This is all very dependent on the franchisee though and the consistency across locations is incredibly poor.
With chick fil a, I know that any location I go to will provide great service and food. On top of that, I like to patronize chick fil a because I know the workers arent being ruthlessly exploited. Sheetz (a western PA gas station, like WaWa) generally seems fall into this category as well.
Next up is Costco, the store shits on most wholesale super markets. From what I've always heard they seem to take care of employees better than most comparable stores as well. Same thing for target (although I've started to see more complaints about target than usual).
My job involves a lot of driving, and I often see dollar stores in the rural areas that have little other options. People hate these stores but have no choice. I imagine that if a small supermarket opened close by that paid employees well/took care of them and had the essential items households need, along with some kind of consignment section for local farmers/producers it would do pretty fucking well (most people in these rural areas will have chickens, goats, cows, bees or whatever and sell excess eggs via a sign at the mailbox staying $2/dozen fresh eggs that could be sold in this theoretical market).
The attack on the working class and labour seems to be opening up a huge potential for new business where employees are actually taken care of, so they actually care about the business and will provide a far superior service/product. People will actually want to patronize the store because they know it isn't exploiting their neighbors that work there and the community by draining everyone's pockets and sending that money off to corporate to be kept overseas in a tax haven with no local reinvestment.
If you had a store like this that paid people well, provided good quality items at a decent price and reinvested in the community to some extent, I think it would honestly do incredibly well. I hope one day I have some capital of my own and can pitch this idea to make it a reality. It's only the greed of a select few that just want to cash out big time in the short term that fucks everyone else over.
